(4) if using the semi-autogenous mill, the large ball with the diameter of 100-150mm can not only reduce the unit consumption, but also increase the handling capacity, but as a result of the casting process defects, the breakage rate of cast ball is much higher than the forged ball.
A ball mill is a drum-grinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. then the grinding media are again below.
After heating, the qualified molten iron is poured into the steel ball metal mold or automatic steel ball production line’s mold when the molten iron temperature reaches above 1550°c so that meets the technical requirements. after molding, then start to heat treatment. it includes quenching parts and tempering parts. for quenching, it also divides into oil quench, air quench according to the different composition of balls.
After the raw material melt and the composition of molten iron accords with the standard of grinding ball production, then start to manufacture grinding balls, we call this process as molding. the balls producing size is from dia10mm to dia150mm, also includes casting cylpebs, and the chrome contenting is …

Cast iron begins its life as pig iron, which is remelted and often combined with large amounts of scrap iron and sometimes with steel. contaminants are removed from the melted pig iron, and the iron, once melted, is then cast. casting is the process of pouring the iron into a mold thus giving it a shape.
Cast iron is an iron alloy containing 2 wt.% – 4 wt.% carbon, 1 wt.% – 3 wt.% silicon and smaller amounts of minor elements . in comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content. cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before being cast.
